What is a hip-to-gable loft conversion?
A hip-to-gable loft conversion replaces the sloping side (the hip) of a semi-detached or detached roof with a vertical gable wall. This extends the ridge and creates enough space for a staircase and a full-size room, usually combined with a rear dormer.
How much does a hip-to-gable loft conversion cost in Eccles?
In Eccles, a hip-to-gable loft conversion typically costs £51,500–£73,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Prices across the North West are typically 6% below the UK average for this kind of work, which is reflected in the range for Eccles. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A hip-to-gable with rear dormer | £51,500–£73,500 |
| Higher specification | £73,500–£92,000 |
Your quote will depend mainly on:
- Scaffolding to three sides
- Size of the rear dormer
- Roof tile matching
- Gable wall construction and finish
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a hip-to-gable loft conversion in Eccles?
Whether you need planning permission depends on your house and its location in England. In England a hip-to-gable conversion is often permitted development within the 50 cubic metre roof volume limit for semi-detached and detached houses, provided the gable does not face a road and the house is not in a conservation area.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
We check this for your address before design work starts, so there are no surprises later.

Questions about hip-to-gable loft conversions in Eccles
How long does a hip-to-gable loft conversion take in Eccles?
Typically 7 to 10 weeks on site. Design and approvals beforehand usually take 6 to 12 weeks.
Is a hip-to-gable better than a dormer?
On a hipped roof, a dormer alone often leaves too little space for stairs. Combining hip-to-gable with a rear dormer gives the most room.
How much does a hip-to-gable loft conversion cost in Eccles?
In Eccles, a hip-to-gable loft conversion typically costs £51,500–£73,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Your fixed price depends on the survey and drawings.
Will it look strange next to my neighbour?
On a pair of semis the roofs will no longer match unless your neighbour does the same. Many streets already have several converted roofs.
Is a hip-to-gable conversion permitted development?
Often yes in England, within the 50 cubic metre roof volume limit for semi-detached and detached houses. It is not permitted development in conservation areas or where rights have been removed.
